SPECIPICATION`fo'ming part of Letters Patent No. 341,&05, dated May 4,1886.

Application filed February 19. 1886. Serial No.192,549. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK CHAPMAN, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedStreet-Washer, of which the following is a full, clear, and exactdescription.

My invention relates to the water-pipe con nections and appliancescommonly known as street-washers; and my invention consists of theconstruction, arrangement, and combination of parts, all as hereinafterdescribed and claimed.

Reference is to be had to the acoompanying drawngs, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

'Figure 1 is a sectional elevation of my invention. Fig. 2 is aplan'view of the same, the top of the main box and the cap beingremoved; and Fig. 3 is a plan View of the cap.

A represents the main box of the street- Washer, to be set in the groundor pavement immediately over the water-main or servicepipe B, and closedby a removable plate or cover, C. The box A and pipe B are connected bya pipe, D, to the upper end of which a hose or hydrant maybe attached..The connection of the pipes B D is fitted with avalve, E, which iscovered by the box F. The upper main box, A, is formed with adepression, G, in its bottom, and surrounding the depression G is thefiange or collar H. In an opening, J, in the depression Gr is fitted theupper end of the tube or shell K, which leads to the top of the box F,and in the tube or shell K is placed the rod L, which connects with thevalve E,

and is made square at its upper end to' receive a key for turning it foropening and closing the valve. A stop plate or yoke, M, is placed uponthe rod L, formed with the opposite projections a a, which act betweenand upon the opposite sides of the fixed studs b b to limit the rotarymovement of the rod L. The yoke M and studs b are protected by theabovementioned fiange or collar H,which surrounds and rises above them,as shown in Fig. 1, and

covering the flange or collar H and the parts contained therein is thecap N. Thisis formed With the central aperture, (l, to expose the upperend of the rod L, and is held in place by the pins c c, which passthrough small holes made in the cars d' d', formed at the edge of thecap N, so that the cap is held securely in place and prevents dirt fromentering the collar H, depression G, and pipe K, and interfering withthe free movement of the rod L and stop plate or yoke M.

Constructed in the manner described, the street-Washer is not onlywholly protected from becoming clogged by the entrance of dirt to themovable parts thereof, but is practical and cheap to manufacture.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. The box A, formed with the npwardlyprojectingfiange H, surrounding the opening in which the shell K is fitted, incombination with the cap N, Secured to the bottom of the box A, over thefiange H, substantially as and for the purposes set forth.

2. The box A, formed with the depression G, aperture J, collar or flangeH. and studs b, in combination with the cap N, the rod L, shell K, andyoke M, placed upon the rod L, substantially as and for the purposes setfortl.
